I 0 all whom it may concern:

Be it known that I, LILLY S. Gnroc, citizen of the United States, residing at Long Beach, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Tatting Shuttles, of which the following is specification.

The present invention relates to a tatting shuttle having special facilities for filling the same with thread or yarn.

It is a known fact that the filling of a shuttle of the usual kind is a very tedious undertaking and can only be done by hand. The object of the present invention is to provide a shuttle with a detachable spool or bobbin which may be filled in a sewing machine in the same manner as the bobbins for the machine are filled, which operation only takes a few seconds. By providing a number of bobbins for each shuttle considerable time would be gained for the user of the device.

In the accompanying drawing one embodiment of the invention is illustrated, and

Fig. 1 shows a side elevation of a tatting shuttle;

Fig. 2 a longitudinal section thereof and Fig. 3 a horizontal section along line 3-3 of Fig. 2 with the bobbin removed and showing the underside of the upper half of the shuttle.

The shuttle consists of a bobbin holder comprising an upper shell or plate 10 and alower shell or plate 11 which are joined together at one end as at 12 forming a sharp point while the other end of the holder is open. At the open end the upper shell 10 preferably extends beyond the end of the lower shell 11 so as to form a short lip 13 covering the end of shell 11. Said lip 13 is a short sharp projection or needle to draw the thread through the loop in tatting and connect one of the scallops with another. At this open end is provided a snap latch or fastener 14 intended to lock the two shells together during operation. The shells are preferably made of fiat flexible material arched in the middle and meeting at both ends to form an approximately elliptical body both in plan view and side elevation. Such material may be metal, aluminum, or fibre or even thin veneers of wood.

On he inner side of each she l is fun nished a small stud or boss 15 situated in the middle of the shuttle and adapted to receive the hollow hub 16 of the spool or bobbin 17 which is revoluble around the bosses. The bosses may be either stamped out of the sides of the shuttle or as shown in Fig. 2 made of separate pieces and riveted to the shells. As will be observed, the bobbin is formed at its ends with heads thickened in such manner that the heads are provided with spherical outer faces of a radius somewhat less than that of the sides of the shuttle so that the bobbin may thus turn freely between said sides.

The flexibility of the shells is such that the bobbin 17 may be easily removed from I the shuttle when the latch 14 is released and the shells opened at that end as indicated. in dotted lines in Fig. 2. The height of the bosses 15 is such that the bobbin may easily be removed.

It should also be noted that the bore of the shuttle is slightly larger than the diameter of the bosses so as to permit the easy rotation of the bobbin in the shuttle.

In using the shuttle it will be evident that the tensioin on the thread may be adjusted to suitably slacken or tighten the same by pressing on the sides of the shuttle as the work progresses.

With a sufficient number of bobbins on hand, the work can be continued longer than what is the case with the usual construction of shuttles.

In case the thread should happen to run off faster than necessary, it may easily be rolled back on the bobbin through the manipulation of the latter with the thumb and finger.

Depending on the character of work for which the shuttle is to be used the size may be larger or smaller within certain limits.

Having thus described the invention, what is claimed as new is:

In a tatting shuttle, the combination of a bobbin holder comprising oppositely curved resilient side plates permanently and rigidly connected at corresponding ends thereof and having their opposite corresponding ends free, a snap fastener com prising a stud and socket each secured to the free end of one of the plates respectively and interengaging for rigidly connecting the free ends of the plates but being freely separable for releasing said free ends of the plates from each Othl, a bobbin dis:

posed between the plates and having a tubu lar hub provided at its ends with heads having spherical outer faces of. a radius less than the'curved sides of the shuttle whereby the 5 bobbin may freely turn betweensaid sides, and studs projecting from the plates into the ends of said hub journaling the bobbin and of a length to prevent clearance ol the" ture.
